First frame of BrightnessContrastEffect when opening modal dialog is black
It looks like the first frame of the ClutterBrightnessContrastEffect
when opening a modal dialog (e.g. nautilus about window) is black on master causing a short flicker. Disabling the will_have_no_effect()
check in pre_paint()
seems to fix this. This reminds me of !992 (merged) and might have a similar underlying issue.
